Google’s John Mueller has advised site owners to stick with traditional domain extensions, such as .com, even if it means adding a hyphen, rather than choosing low-cost or spam-prone alternatives.
The comment came in response to a Reddit discussion on September 8, 2025, about whether a short name on a lesser-known TLD is better than a longer, hyphenated one on a trusted extension.
Here’s Mueller’s original comment on Reddit:
Why the Extension Matters More Than You Think
Not all domains start on equal footing. Cheap or poorly regulated extensions often come with hidden baggage. They’re frequent targets for phishing, mass link spamming, and other abuse. As a result, search engines, spam filters, and security services build defensive systems around them.
That defensive posture creates real-world problems for legitimate businesses. Pages may take longer to get indexed. Even well-structured sitemaps can struggle to gain traction. Emails from these domains are more likely to hit spam folders, and chat messages can be flagged or dropped entirely. In some cases, webmasters disavow entire TLDs just to clean up their backlink profiles.
Hyphen vs. Spammy Extension: Which Wins?
If your ideal .com domain is already taken, you have two main choices. You can add a hyphen to secure a standard .com, or you can pick a less common domain extension like .biz, .online, or .shop. Generally, using a hyphen in a .com is the safer choice because it’s more familiar to users, easier to trust, and less likely to be seen as spam.
Established extensions like .com, .net, or .org have decades of stability and strict abuse handling. Adding a dash is a minor compromise compared to the uphill battle of proving your legitimacy on an extension associated with spam.
Another piece of advice is to avoid awkward, long hyphenated names, misspellings, or “clever hacks” just to get a .com (like “the-best-thingamabob) and aim for a brand name that feels natural and isn’t tied up by others. And before finalizing, confirm that the domain is truly on a TLD, not a subdomain rented from someone else’s property.
Why “Cheap” Can Cost You More
Budget is often a big factor when choosing a domain. But the small savings from a $2 TLD can turn into a much bigger loss in time and reputation.
Fighting deliverability issues, chasing indexing, and convincing partners of your site’s legitimacy takes far more effort than paying for a reliable extension upfront.
Price, however, isn’t an SEO signal beyond basic credibility. Paying hundreds for a luxury TLD doesn’t provide ranking benefits once you cross the “trusted” threshold. What matters most is whether the registry actively works to prevent abuse.
What You Should Do Before Buying a Domain
Here’s a quick check that can help you avoid future problems and choose a domain that earns trust from day one.
- Check registry reputation. Look for public reports on spam and abuse for the TLD you’re considering.
- Test email deliverability. A short trial can reveal whether major email providers treat it as suspicious.
- Read anti-abuse policies. Registries that enforce rules help protect all domains under their control.
- Accept the hyphen. A dash in a trusted TLD is less risky than a clean name on a dubious extension.
- Secure variations. Owning key versions of your domain can prevent phishing attempts and brand confusion.
The Bottom Line
Warnings about risky extensions have been around for years. There have been dramatic examples where entire namespaces were penalized because of rampant abuse. One notable case wiped millions of sites off Google’s index after spam dominated a single domain provider.
Anti-abuse services like Spamhaus continue to publish lists of problem TLDs. Yet many businesses still chase short names and cheap deals, assuming the trade-off won’t matter. In reality, these shortcuts often lead to slow growth and avoidable headaches.
Key Takeaways
- Trusted TLDs like .com reduce friction with search engines and filters.
- Hyphens are minor compared to the cost of a bad extension.
- Cheap TLDs often come with abuse history and trust issues.
- Spending more beyond a “safe” TLD brings no SEO advantage.
- Always own your domain and avoid risky subdomains.
